If the Loudspeaker’s impedance is in-between the 

available connections, use the nearest lower imped-

Note 6 on page 6 for additional information.

WARNING: Loudspeaker terminals are hazard-

ous live and present a risk of electric 

shock. For additional instruction on

8. Connect the Loudspeaker hookup cables to the 

MC2152 Negative Output Terminal (-) and Posi-

tive Output (+) Terminal indentified as 2Ω (ohms), 

4Ω (ohms) or 8Ω (ohms) connection to match the 

impedance of the Loudspeaker, being careful to 

observe the correct polarities. Insert the spade 

lug connector or prepared section of the cable end 

into the terminal side access hole, and tighten the 

terminal cap until the cable is firmly clamped into 

the terminals so the lugs or wire cannot slip out. 

Do 

not over tighten.

 Refer to figures 4, 5 and figure E.
